FEB 27-MAR 1, 20248:00AM – 5:00PMAI Headquarters, Lexington, KYCLASS FULL


  • Day 1 – 3: 8:00AM – 5:00PM
  • Day 4: 8:00AM – 12:00PM (practice exam and review)


The Basic Mixture Technician Training course provides detailed, hands-on laboratory training on basic aggregate and asphalt mixture testing for both experienced and inexperienced technicians. Instruction covers the most current AASHTO and ASTM standards used in the asphalt mix design process. The course focuses on giving the students a thorough understanding of each test and related processes, while instructing students on the procedures and techniques which will maximize testing accuracy and repeatability. Students receive training over the entire range of activities related to asphalt mix design and testing: aggregate sampling and batching, testing aggregate properties, mixing, short-term aging, compaction, and testing of loose and compacted asphalt mixtures. Approximately three-fourths of the course time will be spent in the laboratory with the remaining one-fourth spent in classroom instruction. The class size is limited to six students to maximize each student’s time in the lab with instructors.

This course is intended to complement the Asphalt Institute’s Mix Design Technology course which focuses on how advanced technicians, designers, and/or engineers use laboratory and project information in the mix design process to create long-lasting asphalt mixtures.

Practice Written Exam and Review (DAY 4)

The last segment of the course is devoted to a practice written exam intended to test the student’s knowledge of the content delivered during the class. The exam takes 2-3 hours on average to complete and will be followed by a group review of the answers.

Tests Covered in Laboratory Portion of Course:

Every person entering an Asphalt Institute Laboratory space must wear safety glasses and a lab coat. Individuals who wear glasses must wear side shields. AI will supply required PPE, but welcomes students to bring their own PPE to ensure comfort and fit.

Who Should Attend

This course primarily targets new technicians working in an asphalt mixtures lab. Others who can benefit are asphalt technologists, engineers, consultants, scientists, and technicians responsible for asphalt testing, materials approval, specification and quality control for pavements. Knowledge of aggregate and asphalt mixture specifications is helpful but not required. The course may also benefit local and state materials and federal agency personnel, contractors, and university educators.
